Apublisher reports that 45% of their readers own a laptop. a marketing executive wants to test the claim that the percentage is actually different from the reported percentage. a random sample of 190 found that 41% of the readers owned a laptop. find the value of the test statistic. round your answer to two decimal places.

-1.00

Step-by-step explanation:

Given that a  publisher reports that 45% of their readers own a laptop. A marketing executive wants to test the claim that the percentage is actually different from the reported percentage.

Sample size n =190

Sample proportion p = 0.41

(Two tailed test )

Assuming H0 to be true

std error =

p difference = -0.04

Test statistic = p differencce/std error

= -1

Hence test statistic is -1.00

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
